The Elements of Weather

Understanding Basic Concepts
- explain the difference between weather and climate and the factors that influence both of these systems
- identify patterns in air movement
- identify the effects of air pressure


What is Weather?

http://oncampus.richmond.edu/academics/education/projects/webunits/weather/how.html

1. Define weather.The WEATHER is the condition of the atmosphere (or changes in the atmosphere) at a particular time and place.
2. What four factors affect weather.

  • the air
  • the sun
  • water
  • the earth's movement

Weather vs Climate

http://www.bom.gov.au/lam/climate/index.htm
3. What is the difference between climate and weather?
Climate is what you expect; Weather is what you get.


Air Pressure

4. Complete the following chart:


High Pressure

Low Pressure

Air movement (up or down)
.down
.up
Temperature of air
.about 65 degrees
.about 80 degrees
Wind movement at ground
.
low altitude
.
high altitude

Expected weather
.colder
.hotter

Measuring the Weather

Developing Skills of Inquiry, Design and Communication
- design, construct, and test a variety of weather instruments
- use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations


The following web site describes some of the instruments meteorologists use to collect data about the weather.
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/instruments.html
Use the information to complete the chart.
The source of this information is American so you may have to determine the equivalent metric unit to record in the chart.

.Hygrometer
measures the temperature and amount of humidity in degrees Fahrenheit and degrees Celsius.

Clouds

Understanding Basic Concepts
- explain the formation of clouds and the effects of different cloud formations on weather and climate


Use this web site to answer the following questions.
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/clouds.html
1. What are clouds? water snow form together with alot of stuff to make a cloud.
2. Explain how clouds form.
3. What are the 3 "families" of clouds and what do their Latin names mean?

4. Follow the links to learn about each type of cloud and then complete the table on the next page.
To help you identify clouds, download, print and construct the following "Cloud Key".

After completing the chart, you could try a Cloud Quiz at;

Weather Wise

Forecasting

Understanding Basic Concepts
-recognize large-scale and local weather systems
- predict local weather patterns using data from their own observations of weather and from weather reports
- identify patterns in air movement
